HORSE-POWER I-IOISTING DEVICE.

Specification of Letters ?atent.

Patented July 13, 1915.

Application filed August 31, 1914. Serial No. 859,407.

To all whom it may concern:

Be it known that I, EDWARD SoHULTzn, a citizen of the United States, and a resident of Staplehurst, in the county of Seward and State of Nebraska, have invented certain new and useful Improvements in Home Power Hoisting Devices, of which the following is a specification, reference being had to the accompanying drawings, forming a part of this specification.

My invention has for its object to improve the construction and operation of that class of hoisting devices which are actuated by an animal-operated sweep, and which are especially adapted to be used in connection with hay stackers, to the end that a cheap, portable,'positively operating hoisting device may be supplied to the trade, including a readily operating means for instantly releasing the sweep.

Another object is to provide a detent adapted to normally engage the drum operating mechanism having a trip rope enabling the operator to instantly release the drum from the sweep.

A further object is to provide a simply constructed positively operating brake used in connection with the carrier rope to check the speed of the carrier rope when the drum is released from the sweep.

WVith these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views: Figure 1 shows a side elevational view of a hoisting device embodying my invention, with parts broken away. Fig. 2 is a top view of Fig. 1. Fig. 3 is an enlarged detached detail of the detent disclos-' ing the same in engagement with one of the stop bars. Fig. 4 is a perspective view showing the detent in its released condition. Fig. 5 is a detail of one of the stop ears used in the modification. Fig. 6 shows a detached detail of the brake used in connection with the hoisting or carrying rope.

In carrying out the aim of my invention I employ a portable frame including the base $1118 2, which are connected by means of one or more transverse sills 3, 3 and 9, the sill 3 belng indicated in dotted out-line in Fig. 1. These sills 2 have the stake ears 1' through which suitable stakespass in anchoring the sills in position.

Extending upward over the sills 2 and 9 are the corner posts 7 and S, which in turn give support to an upper frame comprising the side members 6, and the end members 4 and 5, this upper frame being braced by means of the brace bars 4:", as shown in Figs. 1 and 2. To further hold the upper frame to the corners members 7 and 8, I employ the tie rods 10.

Revolubly' held within the bearings 40, 10 held to the frame members 9 and 5 is the tubular shaft 5, which ends in the elbow 4;. This tubular shaft has loosely mounted on it a driving sprocket as, from which extends a band 53, carrying a plurality of outstanding arms or lugs 50. Suitably secured to the tubular shaft 5 at a point above the sprocket 48, by means of a clip 11, is the sweep 10. Pivotally held to the sweep 10, as shown in Fig. 8, by means of a joint 13, is a lead bar 12 to which the animal is secured that is employed to actuate the sweep, as is usual in connection with sweep-operated devices. Extending from a point intermediate of the ends of the sweep 10, is a U-shaped bracket 14 formed of a strap metal member bent upon itself to form two parallel bars with an intermediate space between the same, as shown in Fig. 4:. Located near the inner end within the bracket 14 is a stud 15, while secured near the outer end within the bracket 1% is the, eye bolt 16. Pivotallyheld upon the stud 15 is a releasing lever 17 having the ends 18 and 19 curved in opposite directions, the end 18 being pivotally held upon the stud 15.

Carried intermediate of the ends of the lever 17, is a stud 20, While pivotally held upon the eye bolt 16, is an arm 21 having a nosing 22, projecting below the lower edge of the bracket 14, as clearly shown in Fig. 3. Extending from a pivot stud 23 within the end ofthe arm 21, to the stud are the two parallel links 24.

Secured to the lever 17 is a cotter pin 6, while extending from the cotter pin 7) to the eye bolt 16, is a spring 25. This spring 25 normally forces the lever 17 in a downward direction so that the lower ends of the links 24 are held upon the upper edges of the bracket 14 in which position the lower edge of the arm 21 rests upon the outer end a, of the bracket 14, as clearly shown in Fig. 3. In this position of the instrumentalities the nosing 22 projects downward and for ward and is arranged to travel in the path of the lugs 50.

Secured to the upper end 19 of the lever 17 is a trip rope 26, which passes over a pulley 29 secured to the upper end 28 of an eye bar 27, as shown in Figs. 3 and 4. The trip rope 26 is provided with a ring 0, by means of which the trip rope is secured to the lever 17.

In order to add rigidity to the bracket 14, I employ a brace bar 30 best shown in Fig. 4.

Extending from the members 4 and 5, as shown in Fig. 2 .are the two supporting bars 42, to which is secured a cross-bar 43. Held within suitable bearings secured to the members 8 and 4 is the drum shaft 45, carrying a drum 6, about which is wound the hoisting rope 9. To the upper end of this drum shaft 45, is secured a driven chain sprocket 46, and passing over these sprockets 48 and 46 is the chain 47 The tension of this chain 47 is adjusted by means of a tension roller 52 mounted upon the pin 0. The opposite end of the member 43 gives support to a bowed metal band 51 over which the chain 47 slides to hold the same in proper connection with the sprockets 46 and 48.

The operation of my device is as follows: On imparting a rotary movement to the tubular shaft 5, this movement is imparted to the drum 6, through the intermedium of the detent. In regard to this detent it will be noticed in referring to Fig. 8, that the intermediately positioned stud 20 is at a point slightly below a line passing through the stud 15, and the stud 23 so that the greater the strain against the lower end of the arm 21, the more securely will this arm be locked and held. As the animal actuates the sweep 10, the nosing 22 contacts with one of the lugs 50. The drum 6 is then detachably se' cured to the sweep actuated shaft and rotates with the same. As soon as the operator desires to release the carrier rope the trip rope 26 is actuated, which results in the lever 17 being carried into a vertical position, as shown in Fig. 4. In doing this, the nosing 22 of the arm 24 is carried outward and as the bracket 14 extends tangentially in relation to the drum, the nosing 22 is finally carried out of the path of the lugs 50, and thus escapes. As soon as this occurs, the drum and carrier rope are released from. the trip.

In order that the trip rope 26 will not be twisted, as its lower end is rotated by the sweep, I provide the tubular shaft 5 with the pulleys 40 and 41 over which the trip rope 26 passes, this rope at a point between the pulleys 40 and 41 being provided with the swivel, including the members 37 and 38, shown in Fig. 7. This construction permits the lower end of the trip rope rotating while the upper end is held stationary.

While my hoist is especially adapted to be used in connection with hay stacking and may loading devices, the same can, of course, 3e used wherever a drum is employed to actuate a carrier rope in a hoisting operation;

The device is simple and inexpensive in construction, bothdurable and eflicient in operation, and the drum can be detached from the sweep, with ease, accuracy and desp atch.
